Sequences from a US government-funded program to paint a genomic picture of the human gut's complex ecosystem are going public for the first time since the effort started in 2008. Researchers sequenced thousands of samples taken from 300 healthy volunteers as part of the Human Microbiome Project, which is funded by the National Institutes of Health. The genomic information -- results from shotgun sequencing of 690 metagenomes from 300 individuals and targeted 16S sequencing of 5034 microbiomes -- appeared online last week. You can access the whole metagenome data here and the 16S reads here.
A screen of human embryonic stem cell lines finds several that accumulated changes in the gene TP53, including aberrations commonly seen in cancer.
